Pockets of heavy rain for upper North Island

A narrow band of heavy rain is this morning developing over Northland and late morning and into the afternoon it will move across northern Auckland and sweep out eastwards towards Great Barrier Island, northern Coromandel Peninsula and eastern BOP/East Cape.

The area of heavy rain is only a narrow vein of rain within the front.  This is due to the sub-tropical airflow feeding in to the front.  This area of heavy rain could become ‘torrential’ later today which means surface flooding and/or flash flooding is possble in very localised areas in the firing line…thankfully most of this rain will fall out at sea to our east.

As you can see from the Weathermap rain map this afternoon there is a very fine line between a heavy downpour and nothing much.

A small low will also generate at the southern end of this rain band tonight and cross over the central upper North Island – this will see a burst of strong south to south west winds over the upper North Island overnight, mostly belowing damaging threshold but we can’t rule out a couple of powercuts in northern NZ.

Conditions ease on Friday although the windy sou’westers will hang around – surging up again overnight Friday and into Saturday morning.  It’s spring afterall!
